Specification of Letters Patent.

No. 908,236; Patented. Dec. 29, 1908.

Application filed June 19, 1908. Serial No. 39280.

To all whom it may fiOF/l-CKV/b. 1 1.2 so arranged that when the side plates are Be it known that l, REYNOLDS C. FRAMP- secured in position the passages or: grooves on TON, a citizen of the/United States, residing the side plates and on plate register as indiat=Pittsburg, in the county of Allegheny and l cated in Figure 1. I re cap plate is made in State ofPennsylvania, have invented certain the approximateu shape in cross section new and'us'eful Improvements in Burners, of shown in Figure 4, with the lower portion of which'the following is a specification. the recess in the top of the cap extending to The invention relates to burners of the the point 13 (Figure 3), and the ends of the general type shown in the patent to Buerkle, recess are partially closed by the members No, 637,850, issued Nov. 28, 1899, used pril 14, so that a certain amount of condensation marily in instantaneous water heaters, and

may collect in the recess and cool the cap has for its objects; the provision of a burner plate. T he end pieces 14 extend downwardly at each end of the burner as indicated in Figures 1 and 2, and are provided with grooves so that the overflow from the condensation collected in the top of the cap is carried down to a point below the joints between the cap plate and side plates. In order to still further provide for the cooling the cap plate and the upper edges of the perforate plates 4, the air passage 15 is provided (Figure 4) along the under side of the cap, and the side plates 7 together with their teeth 11 engage the outer edges of the perforate plates 4 and serve to clamp such plates wherein improved means are rovided for preventing undue heating of tie cap plate and the perforate plates employed; the provision of'a burner wherein a thorough combustion is insured and all danger of backiiash is avoided and th e provision of im proved means for protecting the perforate plates and joints from condensation from the heater coils and utilizing such condensation for prcventing over heating of the burner parts. One embodiment of the invention is illustrated in the accompanying drawings, where- 1n:

Figure 1 is a side view of the burner,

Figure 2 is a similar view with the side plates removed, I

Figure 3 is an end view of the burner,

Figure 4 is a transverse section through the burner on the line IVIV of Figure 2,

Figure 5 is a side view of the cap plate, and

Figure 6 is a face view of one of the side plates.

Referring to the drawings, 1 is the body portion of the burner, in which the gas and air are mixed and which is designed to be seated upon the supply pipe in the usual manner and which may be of any approved form, 2 is the elongated discharge chamber having closed ends, and the top wall 3, 4-4 are a pair of perforate burner sheets, which may be either of woven gauze or sheet metal pierced with a plurality of small holes, 5 is the cap plate w ich is secured in position on the top wall 3 by means of the screw bolts 6, and 7-7 are side plates which are clamped in osition by means of the transverse screw b0 ts 88.

The cap plate 5 is'provided on each side securely in position over the sides of the discharge chamber 2.,

It will be seen from the foregoing that provision is made for preventing over heating of the upper portions of the burner and for preventing the ilame from th burner from working back adjacent the per; cap plate 5 because of its shape exposes a large area to the cooling action of the air, and this together with the cooling by means of the condensation collecting in the upper portion of the cap and the cooling by means of the circulating channels, prevent the cap plate and consequently the'teeth from attaining an unduly high temperature, so that the liability of the gas below theteeth 9' and 11 being ignited is reduced to a minimum.

11., is also advantageous, as it provides a large amount of thin metal to absorb the heat of the flame and prevents its burning down into the s ace between the perforate the other renders the casting ofsuch teeth easier and safer, as the height of the separatrallty of grooves 10, while the upper edge of ing ridges of sand in the mold is thus reduced each of the side plates 7 is provided with a by substantially a half.

plate and the si e plates, and the lacing of the teeth partly in one member an partly in ASSIGNOR TO PITTSBURG 'ter with the inclined grooves ofdhe sido/ perforate side sheets, a top wall and end walls, a pair of side plates secured over the perforate sheets and spaced away therefrom, and a cap plate'approximately V shaped in. cross section secured to the top wall and extending to a osition adjacent the uppen edges of thesiclf: plates.

illustrated its use, what I claim as new and desire to secure by Letters Patent is the followingz- 1. In combination in a burner, a discharge chamber having closed ends and top and op posite perforate sides, a side plate secured I over each perforate side and spaced therefrom, and a cap plate secured to the top of the chamber and extending laterally over the upper edges of the side plates.

2. In combination in a burner, a discharge chamber having closed ends and top and opposite perforate sides, a side plate secured away over each perforate side but spaced away! chamber whose walls comprise two opposin perforate side sheets, a top Wall and en walls, a pair of side plates secured'over the perforate sheets and spaced away therefrom, and a cap plate approximately V sha ed in cross section secured to the top wal s and provided with teeth on its outer surfaces adacent the u per edges of the side plates.

9. In com mation in a burner, a discharge chamber whose Walls comprise two opposin perforate side sheets, a top wall and on walls, a pair of side plates secured over the perforate sheets and spaced away therefrom, and a cap plate approximately V shaped in cross section secured to the top wall and extending to a position adjacent the upper edges of the side lates, and means at the ends of the cap late or holding any condensation therein co ected until a predetermined level I is reached.
